what type of league is this? and what is your pitching like?
no top tier closers but a couple that would be nice middle-tier
I don't understan how all these guys went undrafted! in most of my leagues you can't even get most of the replacement closers.. i.e.
valverde, marte, hawkins

They're close for sure, but Patterson is on the much better offensive team and has a bit more power. I would look for around the same number of runs (maybe 5 or so less), 10 more homers from Patterson, 15 more rbi, 5 more steals but maybe 15 points less ba.
